I had the head off of my 94 civic 1.5 milled because the head gasket blew and I want to adjust the valves before I put it back together. However i'm unsure of the gage dimension (feeler gage)and when to adj. What valve. The machinist told me intake open exhaust closed but to me that sounds shadetree and I don't do things like that. Please help

You set the cylinder that you want to adjust to TDC then you adjust all the valves in that particular cylinder.

So set it to tdc for cyl 1, adjust the valves, tdc for cylinder 2, adjust those valves and so on.

There is a quick trick I can teach you, but its hard to explain through the computer and you'd really have to have a good feel for it to do it properly.

Make sure the motor is cold when you adjust the valves.
